Ten self-fertile commercial sunßowers cultivars were evaluated for seed set with and without exposure to bees. In the Þrst planting, the number of foraging honey bees was smaller than in the second, and seed set for most cultivars did not differ between those bagged to exclude bees and ones that were open pollinated. In the second planting, however, a majority of cultivars had significantly gre...

Experiments were conducted at the CSIR-Crops Research Experimental station at Kumasi, Ghana, to determine the effects of seed sorting and planting device on yield of maize in the 2014 major growing season. Two jab planters were used to plant sorted and unsorted seeds. The control treatment was cutlass planting of unsorted seed. One of the jab planters was imported from China; and the other was ...

Key planting factors that influence corn stand establishment includes uniform depth and spacing of seed, correct seed population and optimizing the soil environment for rapid germination and uniform emergence. Other variables affecting stand establishment are seedbed quality (including soil moisture and temperature), seed quality and planter speed. Differences among fields for stand establishme...

Stand establishment problems occur frequently in Arkansas rice fields and are commonly associated with cool soil temperatures (early planting) and saturated soils. There are several factors that affect rice stand establishment including diseases and insects. It is important to understand what pathogens or pests are the cause of stand problems in rice for managing stand establishment problems. I...

A field experiment was conducted at the `Research Farm` of Regional Seed Production Office of Lal Teer Seed Limited, Dinajpur, Bangladesh during November 2008 to April 2009. The study was conducted to investigate the effect of bulb size and planting spacing on seed production of cultivar Taherpuri onion. Three bulb sizes [small (5±2g), medium (10±2g), and large (15±2g)] and four planting spacin...

However, its commercial success as a biofuel plant is still elusive. Major bottlenecks for the same are significant variations in seed yield and oil content, low seed viability and germination rate. For vegetative propagation to be successful, it would require availability of quality planting material throughout the year. However, this is limited by unavailability of quality planting material a...

Delserone, L. M., and Cole, H., Jr. 1987. Effects of planting date on development of net blotch epidemics in winter barley in Pennsylvania. Plant Disease 71: 438-441. The influence of planting date on fall and spring net blotch epidemics (caused by Pyrenophora teres) was evaluated with the winter barley cultivar Pennrad. Experiments were conducted in Centre County, Pennsylvania, in 1982 and 198...
